My invention relates to an improvement in road machines and more particularly to an improved machine for grading roads.

In'thegrading of roads; whether on new damaged roads, it is customary tdutilize tools for rooti'ng-"up or se-arif'ying -the surface and a blade for distributing' and levelling'bffrnaterialf *Heretofore it has been customary to -pro vide a machine equipped with a blade adapted to accomplish the distribution and levelling1of"1naterial* and to provide some v other machine with the means fo r 'sca rify-r ing, ;a result, thescarlfylng and distribution and levelling-cannot be accomplished" effectively in succession, it 'being necessary to first scarify and then distributeandleve with the useof'separatemachines I New it"istheobjeet of invention to provide a inachineWhlc h wil-l i'include in its structure,]both searifyingftooil's"and fa scraper bl-ad'eso mounted asto be sci-apnea for use, separately or "simultaneously and which" further "will be so mounted as to ena ble them to be separatelyor simultaneously manipulated to the greatest advantage;

Further 3 objects: of my invention are to provide a maehi'neof the-"character described, which will 'beof generally iinprovedistruo ture and: which will 'beof maximum'dur- 'a'bilityand efficiency for the uses to which it isintended'tobe put;

1 V Having-nowind eated; 'in'a general Way, the nature and purpose of I'my invention, I will proceedto' a detailed description of a preferred embodiment thereof; with reference to Fig.1 1 is a sideelevation "ofa road gradjg'maeh ne lmb y smy n w 'thesearifying-tools and"'scraper bar in inactive "position. s

the accompanying drawings in The m ac'hine embodying my invention? comprises essentially a frame a-su'pported on a front axle b and; a rear axle c, upon which;

The front axlev 1s,

are mounted wheels at. turnablerelative to the frame through a fifth wheel a and vertical pivot f, while the rear axle maybe turned relative toi'the frame; a

or-shifted laterally with respeettheretoby manipulation of suitable mechanism, knoWn in-the art, and controlled by lathe usual hand wheels 9 and h; 1 v

' Mounted on the pivot f and extending;

rearwardly is abraclret 'z', upon-which is rotatably niountecl a bracket j secured :to

"the forward end ofIa'V-shaped draft 1ne1nher v Connection between'the bracket-j and i the bracket z'j is' n'iade tlrrough a coil spring m embracing-bracket i and abutting against a collar alsecured thereon, sothat I the draft on member/a is' through spring at; The draft-meinberw-lc is, it will :be noted,"

turnable aboutpivot e-andwalso about bracket 7 Secured transversely of nielnben 70,' adends oflinks p, the other ends ofwhiieh are secured 't'o'cranks q onthe endsof shafts-1' adapted to. be rotatedbymeans offhand "Wh'eelss through Worms and gears-t3 s It will jacent-itsrear endyis an anglebar oywhich 1s engaged ad ace'nt each of its ends by the be observed that through manipulation of hand wheels s the a member 7a may; be tipped one Way or the other-through rotation about bracket 2'.

' Adink M is connected at one end to the bar 0 through an extension of its-send 1 -through a slot 4;, and at its otherend to a nut winthreaded engagement" withga-screw 03," mounted transversely of frame a above bar 0. Screw m is adaptedto.bewrotated loy means' of a hand wheelg on a shaft z con- 'nected to" a screw thmu h bevel qgears 1.

It'wi'llbeobserved that if hand wheely be rotated, rotation of' screwswwill be effected and nutw willtravel thereonycausing bar of and the-rear end of member Z: to be moved laterally through rotationabout pivot e.

Guided by brackets 2, depending fromlneniv s V her hand bar 0, is 'acircle' 3 having a gear 4 on its upp er surface'a'nd providedwith a series of spaced hOlesS-adjacent'its periphery, which elements form a turn table. A

gear '6 on'the end of a shaft 7 supported by member 7a meshes with 'gearf' on circle 3 and may be actuated to rotate circle 3iby a by means or" notched shoes 25 and bolts handle 8 on a shaft 9 connected to shaft 7 I through a universal joint 10.

The. circle may be retained in any adjusted position by means of a pin 11, passed through suitable holes'in one of the brackets 2 and one of the holes 5 in the circle.

Secured within the circle is a circular angle member 12 beneath which are secured transversely extending channel members 13,

one of which extends centrally of the circle 9 u and is connected to bar 0 by means of a.

pivot pin 14, which, through the member 13, serves to support the circle clear 'ofwits guiding brackets 2. Adjacent the ends of member 13, which extend beyond the circle 3, and secured transversely thereof are a pair of angle bars 15, which, as will be observed, extend longitudinally of the ma chine.

To the sides which are in turn secured to a scraperbar 17 ad acent its ends, as shown in Fig. 4;

i The brackets 16 are provided-with a. series serve tobrace the brackets and thescraper of holes 18, and links 19 are pivotally secured to the bars "15 adjacent their rear ends. The links 19 are adapted to beconnected to the brackets 16 by means of pins 20 which may be passed through any one of the holes 18' in; the brackets. .The links bar supported thereby in desired-working posltion, as shown 1n Fig. 4. WVhen, however, it is desired I to render the scraper inactive, it is lifted and the bracket secured directly to bars 15 bypassing the pin 20 through the brackets and through holes '21 provided in the bars 15, as shown inFig-l 1; v A pair of brackets'22, similar to brackets 16, is pivotally secured to bars 15, ahead of their centers, and are connectedby a transversely extending bar 23 of channel section. The sides of the bar 23 are notched at intervals for the receptionxof picks or scarifying tools 24, which areclamped to the bar '26. Links 27 are pivotally secured to bars 15,. adjacent their forward ends,. and are adapted to 'be'connected to bracket 22 by pins 28which are passed through oneof ,a

series of holes'29 in I the brackets. The links 27 serve to brace the bracketsand bar 23 to retain'the scarifying toolsin adjust able workingposition, as shown in Fig.4. When, however, it is deslred 1 to render the scarifying toolsinactive, the bar 23is lifted and the brackets secured directly to bars 15 by passing pin 28 through the brackets and throughholes 30 provided in .bars '15, as shown in Fig. 1.;

. From the above description, :tion'and advantage of the machine embodying my invention will, it is believed, be. apparent."

i the opera- It will be particularly noted the of bars 15 tothe of their centers, are pivotally secured brackets 16,-

circle 3, supported from the draftmember 7 7a and from which the blade 17 andv scari-' tying tools 24 are supported, is movable laterally and "also may be tipped, thus enabling 'all desired adjustment of the'tools and blade." It will be further noted that both the blade 17 and the scari'l'ying tools. 24: are supported from the same circle; however, being adjustable working positions or into inactive position wholly independently of one another, thus enabling either the blade .or the scarifying each side connected to the ends of the last mentioned cross-members.
